In this structured inquiry lesson, the students will explore several simple machines and their functions. They will also use a new measurement tool, a spring scale. They will collect and analyze data as they compare the force required to lift a load (a water bottle) without and with the assistance of a simple machine. Students will create a double bar graph to aid with data analysis. Students will investigate the question: “How does using a tool affect the amount of energy required to do work?”
